Prior to 7.3.2, Astro's JSX and MDX rendering pipeline treats string children of script and style elements as trusted HTML without distinguishing compiler-generated literal content from dynamic expression values. An application that passes attacker-controlled data directly as a dynamic child can allow a value containing a closing script or style tag to terminate the element and inject arbitrary HTML and JavaScript. Other JSX expression contexts escape dynamic strings automatically; the issue is limited to script and style children rendered through the astro:jsx renderer, including MDX components. Successful exploitation can produce reflected or stored cross-site scripting under the application's origin. This issue is fixed in 7.3.2.","state":0,"publishedAt":"2026-10-21T18:17:25.507+00:00","modifiedAt":"2026-10-23T15:17:25.413+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N","score":6.5,"severity":"MEDIUM"}],"references":["https://github.com/withastro/astro/commit/a548223607b9bb146d5d90ddda495343f9a2a739","https://github.com/withastro/astro/pull/17896","https://github.com/withastro/astro/releases/tag/astro@7.3.2","https://github.com/withastro/astro/security/advisories/GHSA-98hj-9722-w3j8"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-114128","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-79"],"productCriteria":[],"sourceDates":{"published":"2026-10-21T18:17:25.507","lastModified":"2026-10-23T15:17:25.413"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
